Kelly Clarkson: I'm Not Gay!

And she may not hook up and she may be singing about a guy who is a "know it all" these days. But the singer wants to make one thing clear: she's straight.

"People keep saying I'm gay, and I'm not," the original American Idol tells E! News. "I'm pretty sure I've never made out with a girl. It's just not helping me because I'm straight. No boy wants to hit on me because I make mean songs about them, and they think I'm gay."
